EGG-BEATER.

specification of Letters Patent.

Patented Aug. 6, 1912 Application filed January 2,-1912. Serial No.8%,924.

To all whom it may concern:

Be it known that I, SIDNEY A. GRANT, a citizen of the United States ofAmerica, and resident of Thonipsonvil'le, in the county of lartford andState of Connecticut, have invented certain new and useful Im rovementsin Egg-Beaters, ofwhich the ollowing is a full, clear, and exactdescription.

This invention relates to improvements in egg beaters of a kindcomprising frames or blades which are revoluble about a centralizedvertical part and which comprise means for causing the rapid rotativemovements of such frames.

An object of the invention is to provide an egg beater of the generalclass to which this invention relates, with a foot-piece of such shapeand character that it forms a reliable base support for the beaterirrespective of the form or nature of the utensil in connection withwhich it is used, and which foot piece is also cooperative with therevolubly bladed machine to secure a quicker and more thorough eggbeating action.

Another object is to construct the centrally rotative spirally ribbedshaft of the egg heater and skeleton frames carried thereby from wire ina most simple manner whereby the manufacturing cost of the device isgreatly reduced.

Other objects are for minor improvements of the device as will behereinafter rendered apparent.

The invention is described in conjunction with the accompanying drawingsand is set forth in the claims.

In the drawings :Figure 1 is an elevationof the improved egg beatershown as in use in a bowl having the handle thereof in central verticalsection. Fig. 2 is a cross sectional view on line 2-2, Fig. 1. Fig. 3 isa cross sectional view enlarged as seen in an upward direction beyondthe section line 33, Fig. 1. Fig. 4 is a side view of the foot portionof the heater in a compressed condition.

Similar characters of reference indicate corresponding parts in all ofthe views.

In this egg beater, paired wire members a a are twisted about each otherfor a portion of the lengths thereof to form a spirally ribbed shaft A,the cross section of which is comprised in two adjoined circles as shownin Figs. 2 and 3.

The end portions of one of the wire members a are extended transverselyrelatively to the lower portion of the shaft A and bent to form askeleton frame B at one side of the shaft, the wire being transverselycontinued in the portion b to the other side of the shaft and bent toform the skeleton frame B opposite the one B, the extremity of such wirebeing formed as eye 0. The other one of the two wire members has thedownward extension d between and terminating near or below the bottom ofthe opposed frames B, B and around which, a short distance above itsfree end the eye formed extremity c of the other wire has an encirclingrelation to form a shoulder or stop.

The extremity of the central and clownward extension of the wire belowthe aforementioned shoulder for the coil or eye receives connectiontherewith of a foot piece D wh ch is made as a spring having the form ofthat sometimes termed a valve spring, that is, it is a spring comprisingcoils having a rising relation one to the next and each successivelydecreasing in diameter so that the spring foot piece is of anapproximately conical or inverted cupshape; and its uppermost coilterminates in a small eye 7 which encircles the downwardly extendingportion of the wire comprised in the spiral shaft and is retained inplace thereon by a washer 9 held in place by the opposite or headed end72. of the wire.

The foot piece, as manifest, is susceptible of compression from itsexpanded condition shown in Fig. 1 toits compressed condition shown inFig. 4. i

The handle F of the egg beater is made with the bore or chamber mtherein which opens to the lower end of the handle proper and it has aclosing cap n at its lower end provided with an elongated opening 0through which the wire formed spirally ribbed shaft has a rotationimpelling engagement, when the handle is vertically moved relatively tothe shaft as common in spiral tool drivers,the handle being firmly heldagainst rotation, the shaft necessarily rotating under the reciprocationof the handle relatively to the shaft.

W'ith the foot-piece resting on the bottom of a bowl or dish the forcingof the handle downwardly causes the rotary motion of the spirally ribbedshaft and the frames therewith in one direction, and insures a maximumcompression of the spring, t, which is in' closed in the hollow handleand is in reaction in a downward direction against the shaft; then whenthe hand pressure is relieved the reaction of the spring causesrelatively an upward movement of the handle for the reversed rotation ofthe egg beater,-this mechanical action being a familiar one as exemplified in spiral tool drivers.

Provision of the foot-piece ofthe inverted cup-shape insures asatisfactory bottom support for the eg beater even wherethe lower endthereof is held against the bottom of a bowl of convex form asrepresented in Fig. 1; and by the manner of engagement, as statedbetween the. lower extended part of the shaft and the foot piece wherebythe one may rock relatively to the other, the user of the device isrelieved of the necessity for care that the same be held in a perfectlyupright position.

As represented in Fig. 1, the spirally .ribbed shaft, the opposedrevoluble frame and the bottom extension d are all constituted by asingle length of wire, the manner of bending which is apparent.

It will be manifest that when the egg beater is operated, for instance,in a bowl in which the material to be beaten stands only up to acomparatively low level, the downward pressure exerted in the drivingaction will serve to compress the spring foot piece D so that the bladesare low down in the receptacle for the assured beating up of the eggs,the white or yolk only of an egg or the other matter to be subjected tothe beating action; and, furthermore, the action of the spring footpiece of compression and expansion is an auxiliary, for the beatingaction, to the revoluble blades.

For-a suitably broad rest for the lower end of the spring t, the upperextremity of the spirally ribbed shaft has a cylindrical head u of leador other metal cast thereon; and in the comparatively short spacebetween the head and the cap at is a cushioning spring 41 which on theupstroke of the handle prevents the cap from being brought to contactagainst the head.

I claim 1. In an egg beater, in combination, paired wire members, whichfor portions of the lengths thereof are twisted about each other to forma spiral shaft, the end portion of one of the members being extended andbent to form a skeleton frame at one side of the spiral shaft, andtransversely continued and bent to form a skeleton frame at the otherside of such shaft, while the other wire memher is downwardly extendedbetween, and below the bottom of, such opposed frames, and provided witha foot-piece with which it has a rotative, and also a rockingengagement, a hollow handle having a closing cap at its lower endprovided with an elongated opening through which the wire-formed spiralshaft has arotation impelling engagement, and a spring in said hollowhandle reacting downwardly against the spiral shaft.

2. In an egg beater, in combination, a single length of wire,intermediately doubled on itself and the adjacent paired wire membersbeing for portions of their lengths twisted the one about the other toform a spirally ribbed shaft, the end portion of one of the membersbeing extended and bent in the form of an elongated coil to form askeleton frame at one side of the shaft, such end portion, furthermore,being transversely continued and bent to form' an elongated coil at theother side of the shaft, while the other wire member is downwardlyextended between, and below the bottom of, such opposed coils, andprovided with a foot-piece with which it has a rotative, and also arocking engagement, a hollow handle having a closing cap at its lowerend provided with an elongated opening through which the wire-formedspiral shaft has engagement for a rotation impelling effect, and aspring in said hollow handle reacting downwardly against the spiralshaft.
